Description

PTFE oil seal occupies a large position in mechanical parts. It is to replace lip rubber oil seal, and successfully solve the problem of rubber framework oil seal leakage and oil leakage. PTFE oil seal has the property of free expansion after drawing, the friction heat produced in the work so that lips will constantly shrink, so do not need the help of spring, it will be tightly held on the shaft, do not let it and the shaft surface gap exists, and can compensate for wear.

Advantage

• The inner wall of the PTFE oil seal is engraved with a thread groove opposite to the axis. When the axis rotates, it will produce an inward thrust to prevent the flow of fluid. This thrust is so high that it can seal 1.0MPa(single lip), 3MPa(double lip) fluid pressure, rubber oil seal is only 0.03MPa.
• Ptfe oil seal has the best friction resistance, especially suitable for no oil or less oil state of work, even after a long shutdown again, can immediately have low friction characteristics.
• rubber oil seal with spring pressed lip mouth, and the contact surface width of the shaft is only 0.3-0.5mm PTFE oil seal with a wide lip dynamic structure without spring, and the contact surface width of the shaft is 5-7mm, so that you can keep a sufficient oil film, and the eccentric shaft is not sensitive, in the radial run out of 0.4mm working condition can still work normally.
• PTFE oil seal can be done without leakage.
• Teflon oil seal is especially suitable for high-speed rotating applications, the speed can reach 30m/s.

Application

PTFE oil seal is mainly used in automatic precision machinery, robots, gear boxes, air compressors, air conditioners, pumps, motors, engines, mixers, pharmaceutical and food processing equipment, chemical processing equipment and so on, especially suitable for traditional rubber oil seal can not meet the application.
